To all whom it rmty concern:

Be it known that I, LUOIEN S CRANDALL, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Mechanical Calculatorsand Recorders, of which the following is 'a specification.

My present invention relates to mechanical calculators and recorders andto that class of calculators and recorders in which the numbers to berecorded and totalized or subtracted are'determined by depression ofselected keys of a series of keys arranged in a suitable number of rowsof tenkeys, each row representing the denominational value of thefigures to be printed or recorded by the depression of any of its tenkeys'-'i. a, hundredths, tenths, units, tens, and so on.

In the present invention it is my object to provide mechanism wherebythe registering or recording operation, or both, are completedsimultaneously with and solely by the dcprcssion of a key.

In machines of thischaracter it has-been proposed also when it isdesired to subtract one number from another to progress a registcringorrecording dial or dials or other medium oi register or record until thesame indicates the digit or digits of lesser unitary value desired, atthe same time dogging or throwing out of operation the carryingmechanism to prevent the feed or progress of theindicating dial or dialsor other instrument of next higher value.- This unnecessarilycomplicates the mechanism. in the machine constructed, in accordancewith IIIy-lIIVOTItlUIF subtraction is accomplished by a simple device ordevices for reversing the register mechanism.

Further features of my invention are improved means whereby therecording deviee may be thrown out of operation, so that the registermaybe used alone, and means whereby the register may be thrown out ofoperation and the recording device used alone and means preventing theactuation of the register by the adding devices and the subtractingdevices at one and the same time.

With a machine constructed in accordance with my invention it ispossible to record a series oi numbers on the recorder which may beadded and from which other numbers may the platen-sparing pawl.

be subtracted, the result, whether sum or remainder, being indicated onthe register, to

suspend actuation of the register so that such result may be transferredto the recorder, to return the register-dials to their zero positions tobegin a new operation, or to continue the old calculation by allowingthe result obtained to remain on the register-dials.

My invention further consists inmany improved details of constructionhereinafter de scribed, and shown in the accompanying drawings, in whichlike reference-numerals refer to like parts, and in which Figure 1 is atop plan View, partly in section, of a mechanical calculator andrecorder constructed i'n accordance with my invention.

The key system-Referring now'in detail to the drawings, 1 represents thecasing of my improved calculating and recording machine, having mountedthereon a series of key-bars 2, having at their upper ends keys 3 andarranged, preferably, in eight longitudinal rows of ten keys each,although an number of suchrows may be employed, eac rowrepresenting thedenominational value of a number registered or recorded by thedepression of any one of its ten keys-that is, tens, hundreds,thousands, or other denominationand each of the said keys being numberedand representing a numerical value ranging from 1 to 9 and 0'L. 6.,

there being a lateral row of keys for each' number from 1 to 9 and 0.The

key-bars2 are mounted vertically in the ma-- suitable indieia thereon.

Each of the sleeves 5 is loosel mounted on the rock-shaft 6 and, asstate is provided with a finger or projection articulating with a keyornotched-faced collar 7, rigidl mounted upon the rock-shaft 6.Rock-shafts 6, of which there are ten in number, one for each lateralrow of keys, are controlled by any suitable form of spring, suchas'sprin s 8, mounted on the end of said shafts an secured at one end tosaid shaft and at the other end to the side of the casing 1. Adepression of any key will rotate its key-faced sleeve 5 on the shaft 6beneath said key. Such rotation of the sleeve will through engagementwith the collar 7 described rotate the shaft in the direction of thearrow, Fig. 1.

The printing or recording systein.-One of the collars 7 on each of theten shafts 6 is provided with an upwardly-projecting arm 10, which isconnected, through means of a sliding bar or pitman 11 having a rack 12on its forward end, with pinion-teeth 13 on a crankarm 14,pivotallvmounted on a curved rod or shaft 15, suitably seated or mounted in therear part of the machine. There are ten crank-arms 14, each of which isconnected in the manner described to one of the shafts-6, so that eachis controlled by a lateral row of keys. Each crank-arm 14 has pivotallymounted thereon a type-bar 16, at the upper end of which is a type-head17 with a character thereon. The teeth 12 on bars 11 are held inengagement with the pinion-teeth 13 on the crank-arms 14 by aguide-wheel 18,

. suitably positioned beneath the bars or pitmen 11, and upon which saidbars 11 are supported at their forward ends. In this manner each shaft 6is connected to a particular type-bar, the shaft 6 at the extreme frontof t e machine being connected to the first type-bar on the right,(shown in Fig. 6,) the second shaft being connected to the secondtype-bar, the third shaft being connected to I erforations or holes 19will be described ater.

21 is the printing-platen, mounted as hereinafter described.

22 represents a series of inking-rolls of any suitable number, butnumbering five, as shown in the drawings, one for each two or more orless type-bars rotatably mounted on .a bar 23, shown in the drawin scurved to conform to the arrangement oft e type-bars.

Inking-rolls 22 are arranged immediately above and out of contact withthe type-heads 17, so that when the said type-heads are projected intoprinting position they will ass over the surface of said rolls, therebyin ing the type on said heads. Any other suitable means may be em loyedfor ink-ing the said type, or direct in ing means ma be done away withentirely and suitable rib on mechanism substituted.- As the pitrnen 11are shoved forward the teeth 12, engaging the teeth 13' on thecrank-arms 14, rotate said crank-arms, forcing the type bar 16 u wardlythrough perforation 19, the typeead 17 passing over inking-rolls 22. Asthe crank arm 14 reaches a vertical position the typebar 16, which restsnormally in a slanting position, will be vibrated and thrown toward theplaten, striking the same, and thereby making the impression.' Suchmovement of the type-bar being caused by the rotation of the shaft 6 inopposition to its spring 8, the type-bar is returned to its normalposition by the return of the said shaft to its normal position by thesaid spring.

The platen-shiftmg mechanism.-I.n order to determine the denominationalvalue of a' number printed in the manner already described, it isdesirable to shift the position of the recorder-platen 21. This Iaccomplish in the following manner The .frame of the platen-mu-riagecomprises a plate 24, hinged at 25 to a sliding late 26, mounted on aguide-bar 27, seate the machine-casing 1.

in standards 28 29 on Pivotedto standard 29 is a shift lever or handle30, connected to a.

I bar 32. Bar 32 passes through the plate 24,

'ister alone.

which 'is slidable thereon. Such arrangement is provided for the purposeof throwing out the recorder-platen when it is desired to suspend recordtem orarily or to'use the reg- It wil be readily seen that the throw ofthe lever or handle to the rear will carry the platen 21 away from theprinting-point. Extending transverse the machine-casing beneath theplaten 21 and its 7 frame is a slide or shuttle bar 33, carrying 3 hasmounted beneath antifriction-rollers 34. Slide-bar 33 ma be mounted inany suitable manner to slide in either direction transverse the casing1, and, as shown in the drawings, the same is mounted through slots 35'on the flanged guide-rollers 36, mounted on posts 37 on the bottom ofthe machine-casing. Plate 26 of the recorder-platen frame or carriage isconnected to bar through means of a lever 38, pivoted at 39 to a post 40on a frame 41, mounted at the rear of the machine-casing. Lever 38 isconnected at its upper end to the sliding plate 26 by a pivoted link 42and is forked at its lower end to straddle a pin 43 on slidebar 33.

Each of the eight lon itudinal rows of ke Y it above the rockshafts 6 ashuttle-bar 44, extending longitudinally in the casing and provided witha series of pins 45, adapted to engage'cams or' projections 46 onsleeves 5, there being one in 45 for each sleeve 5. At their rear endsars 44 are twisted, so that their faces are parallel with the bottomofthe machine-casmg and slide between and are supported by guide-rollers47, being supported at their forward ends by rock-arms 9,'looselymounted on'a shaft 71. Shuttle-bars 44 are, furthermore, formed withcam-surfaces 48 at their rear ends, each of said bars through its camsurface being in a path to-engage one of the antifriction-rollers 34upon the movement of the said bar. Cam-surfaces 48 face four to theright-hand side of the machine and four to the left-hand side of themachine. Cam-surfaces 48 vary in extent, shape, or size, so. that uponactuation of their respective shuttlebars 44 they will move theSlldG-bfil 33 a distance sufficient to move the platen-carriage to theproper printing position to give the number printed the denominationalvalue determined by the column in which the depressed key is located.

From theforegomg it will be seen that at the same time that the key isdepressed, throwing the proper type-bar into printing position throughmechanism already described, the cam or pro ection 46 on the sleeve 5,partially rotated by the key depressed through engagement with one ofthe pins or projections 45 on its shuttle-bar 44, will force the saidshuttle-b ar forward, throwing the cam-face 48 of said'shuttle-bar intoengagement with its antifrictioneroller Mon the bar 33, so that the saidbar 33 is moved a distance sufficient to move the platen frame orcarriage through the lever 38 to a position to print the number in aposition on the platen which will give it the denominational valuerepresented or determined b the position of the column of keys in whicthe depressed key islocated.

In view of the foregoing mechanism it is necessary that theplaten-carriage rest normally pose I have provided a pair of pivotedarms 49, mounted on the frame 41 and having bearing lugs or projections50 held normally against the lever 38 by the action of springs 51,holding arms 49 normally against stoppins 52 on the frame 41. By thismeans each movement'ofthe lever 38, whether to ri ht or'left, will beino position to one or the ot er of the arms 49, w ich will throughsprings 51 return the said lever to its central or vertical position.The platen carriage or frame being connected through link 42 to the.lever 38 is therefore held normally in a central position on the bar 27.a It is obvious that anymovement of the lever 38 will communicate in acentral position. For this pura proportionate movement to the bar 33, so

that if the bar 33 has been moved to one side or the other of its normalposition to bring the carriageto the desired printing position the saidbar will, with the other parts described, be returned to its normalposition. The shuttle-bars 44 are returned to their normal positions bysprings 44,- secured at one end to the machine-casing and at their otherends in eyes in the said shuttle-bars.

For the urpose of line-spacing on the platen 21 I ave provided asuitable ratchetwheel 53 and beneath the ratchet 53 a pawl 54,havinganelon' ated tooth 54' and pivoted at 55 to t e end 0 a bar 56, pivotedat57 to cars on the machine-casingl. The forward movement of the pawl 54is limited by a finger 58 on'the heel of the said pawl, enga ing a pinor projection on the bar 56. Paw 54 is held normally in verticalposition by a spring 59, mounted on its pivotal pin 55 and secured to apin or projection 60 on the said pawl.

ally connected to the bar- 56 and sliding through a guide-bracket 63.

64 is a coil-s ring mounted on the stem 62, adapted to hold key 61normally in its forward position. I

Stem 62 extends downwardly in the casing toa-point just above thebottomof the cas in ,the downward movement of the said stem 1 being limited bythe end thereof contacting with the bottomof the casing. I

A downward de ression of the key 61 raises the rear endofthebar 56,throwing the pawl 54 upwardly teeth of the ratchet-Wheel 53 to rotatethe platen 21 a distance equal to one line-space.

61 is a space-key having a stem 62 pivotinto engagement with the typewriting construction.

' opposite directions.

The elongated tooth 54' of the pawl 54 is pro-' vided to allow forslight irregularities in the position of the recorder-platen. Theflexible connection between the pawl 54 and the bar 56 described isprovided to allow the said pawl toride over the teeth of the saidratchet upon the return movement of the key 61 under the influence ofits sprin 64. A handwheel 65 is also mounted on theplaten 21, so thatthe same may be turned forward or backward, as desired, for the purposeof spacing, making corrections, or any other reasons. Any other suitabledevices may be used in connection with the recorder-platen carriage,such aspaper guides, rollers, and other attachments common totheordinary Other means may be used for line-spacing and for shiftingthe platen, if desired.

T he totaling or registering system Each of the key-bars 2 exceptingthe-zero-key bar is provided with a cam-surface 66, facing toward therear of the machine and each enaging an antifiiction-roller 67 onshuttleiars 68. Shuttle-bars 68 are commensurate in number with thelongitudinal rows of keysthat is, one shuttle-bar 68 for thehundreds-column, one for the tens-column, one for the units-column, andso on. Each shuttle-bar 68 is supported by a pair of rock-arms 69 7 O,the rock-arm 69 bein loosely mounted on a shaft 71 at the front 0 themachine, the rock-arm being mounted on a shaft 72 in the rear portion ofthe casing. vMounted at the upper end of each rock-arm 70 is asubtracting-pawl 73 and an addin -pawl 74, connected by a spring 75 andsli ing in a bifurcated rock-arm '7 6, having a notch 78 in one forkthereof to receive the adding-pawl 74v and a notch 77 in the other forkthereof to receive the subtracting-pawl 73. Rock-arm '76 is rigidlymounted upon a shaft 79, suitably mounted in and extending transversethe casing. Mounted on a shaft 80, extendin transverse the machine, area series of co lars 81 equal in number to the number oflongitudinal'rows of keys employed. Rigidly mounted on or integralwitheach collar are a pair of ratchet-wheels 82 83. The teeth of theratchet-wheels 82 83 project in The teeth of the ratchetwhe'el 82 areadapted to be'e'n a ed by the adding-pawl 74, and the teeth of t eratchet- Wheel 83 are adapted to be enga ed-by" the subtracting-pawl 73in a manner hereinafter described. Each collar 81has also mountedrigidly thereon a transmittingwheel 84, having a crown-gear 85 meshingwith a pinion 86 on a shaft 87. of a register-dial 88. The number ofregister-dials 88 also corre sponds withthe number of longitudinal rowsof keys.

89 isa shift handle or lever suitably pivoted to the machine-casing andpivotally corinected at 90 at its lower end to a bar 91, ex-

engagement with their rearward through rule in the use of tending'rearwardly in the casin and a rockarm 92, ri idly mounted on t erock-shaft 79. The t rust of the handle or lever 89 in the direction ofthe arrow, Fig. 2, throu h the bar 91 and rock-arm 92, rocks the rocshaft 79, elevating the bifurcated rock-arm 76 and raising the pawls 7374, which are held toward each other by the springs 75, and throwing thesubtracting-pawl 73 into the path of engagement with the teeth on theratchet-wheel 83; The movement ofthe handle or lever 89 to the limit ofits throw in the opposite direction will lower the bifur-. catedrock-arm 76 to bring the adding-pawl into engagement with the teeth ofthe ratchet-, wheel 82. The movement of the handle or lever 89 to thecentral or vertical position holds both of thepawls out of the path ofrespective ratchetwheels. The bifurcated rook-arm 76 therefore operatesas a governor to the register mechanism.

Upon the depression of a key 3 the shuttlebar 68 will be forced towardthe rear of the machine a distance depending upon the value of the keydepressed, ,forcing the rock-arm 70 to the rear and carrying the'pawls73 74 guide-notches 77 78 respectively.

For preventing overmotion of the shuttle- 5 bars 68 I provide stop pinsor projections 2' on each of the key-bars 2, which are in line with andare adapted to engage a series of notches 68 in shuttle-bars 68 u on thekeybarsreaching the limit of their dbpression.

The register indicates the result after a series of operations, whetherof addition or subtraction, of all or certain of the numbers recorded011 the recorder; but as a general the machine the register r05 willshow the sum of all the numbers recorded. If it is desired'to transferthis result, Whether it be the sum or the remainder of an addition orsubtraction, to the bottom of the column of figures recorded ontherecorder IIc without adding or subtracting this result to or fromitself onthe register, the handle 89 is movedto its central or verticalposition, as shown in Fi 2, in which case both pawls 7 3 and.74 are eldout of the path of en ager1 ment-With their respective ratchet-whee s,so that by the depression of a key, although displacing the shuttle-bar68 and movingits rockarm 70, no motion will be communicated to thetotal-dial 88, controlled by the operation r20 of the keydepressed,'owing to the fact that the actuating-pawls fail to engage theteeth of their respective ratchet wheels. Such arrangement thereforemakes it possible to recor a series of numbers on the platen'and 12 5then record the result without alterin changing the statement on thetotal-dia s.'

The cmrging mechanism.In order to perform the adding or subtractingoperation necessary in machines of this character, I

have provided a very sim le mechanism consisting in a rock-arm 94,oosely mounted on theshaft 79, carrying at its outer end a pin 95, uponwhich is pivotally mounted a hnk 96, connected directly to one of therock-arms 70. Each of the rock-arms 70 is thus connected to the shaft 79. On the pin is an antifriotion-roller 97, adapted to engage any one ofthe five cam projections 98 on the next adjacent transmitting-wheel 84of lower dcnomination. For the purpose of clearness the transmittin-wheel 84 may be described as being divide( into five segments, each segment including a sufficient number of teeth of the crown-gear 85 torotate the pinion 86 one revolution, each of such segments beingprovided with one of the cam projections '98.

From the foregoing it will be seen that upon a complete revolution ofone of the register-dials of lower denomination the antifriction-roller97 in line with the transmit tingwheel 84, connected to such dial, willbe displaced by engagement with one of the five projections 98 .on suchtransmitting-wheel, drawing the link 96, by means of the pin 95, to therear, ulling the rock-arm'70 of the next higher enommation to the rear adistance sufficient to move the adding-pinion or v thesubtracting-pinion, depending upon which 'riphery of the wheel.

pawl is in the path of engagement with its pinion, a distance equal toone tooth, thereby increasing or decreasing, such as the case maybe thevalue of the number on the register-dial of such higher denomination.

The movement of each of the transmitting- 1 wheels 84 is governed or.controlled by a spring'99, engaginga groove 100 in the pee Springs 99may be mounted in any'suitable manner such, for instance, as on the bar101, suitably supported in the machine. 7 i

The zero-return mechanism.For the purpose of returning the'dials totheir zero positions the following mechanism is provided: A shaft 102,extending transversely in the machine-casing, at the forward endthereof,

has loosely mounted thereon a series of sleeves 1.03, provided withdownwardlyprojccting fingers 104, engaging pins 105 on the shuttle-bars68. The number of sleeves 103 1 is equal to the number of longitudinalrows of keys and to the number of shuttle-bars 68,

there being one sleeve 103 for each shuttlebar 68. Mounted rigidly onthe shaft 102, adjacent each sleeve 103, is a collar 106, having afinger or projection'held normally'in engagement with the notched. endof the sleeve 103 by a spring 107, secured at one end to-the said sleeveand at the other end to the said collar.

108 is an operating-handle mounted. rigon the shaft 1.02 and adapted torock idly said shaft when actuated. A forward pull of theoperating-handle 108 will partially rotate each of the collars 106,which through shuttle-bars is obstructed.

their zero positions,

springs 107 will communicate motion to the sleeves 103, forcing theshuttle-bars 68 to the rear until further movement of the said ofs'ullicient strength, therefore, to move. shuttle-bars 68 until thelatter are obstructed. Inasmuch as the shuttle-bars 68 will not. all. beobstructed at one and the same time, it becomes necessary toprovide theflexible connection between each of the sleeves 103 and the shaft 102.Upon obstruction of a shuttle-bar 68 rotation of the sleeve 1.03,connected to such shuttle-bar,

will be stopped and further movement of the handle or lever 108 willthen be in opposition to the spring 107, connected to the particu larsleeve 103 dogged. As has already been described, the rearward movementof any one of the shuttle-bars arm to the rear, feeding either theadding-or subtracting gear-wheel or neither, depending upon whether the addingor subtracting pawl is in the path of engagement witnits gear-wheel orwhether both are .held out'of the path of engagement. When it is desiredto return all of the register-dials to their zero Springs 107 are 68forces the rockpositions, the adding-pawls 74, through operat'ion of thelever 89, are lowered into the path of engagement with their respectivegearrwheels The handle 1.08 is then drawn forward, throwing all of theshuttlevbars 68 to the rear and feeding each of the dials 88 arounduntil they are stopped at as hereinafter described. Forstopping thedials88 in their zero positions or for preventing overmotion of the samea dog-plate 110 for each of the transmitting-wheels 84 is rigidlymounted upon a shaft 109, extending transverse the machine beneath. thesaid transmitting-- wheels. 'Dog-plates 1.10 will normally be ininoperative position beneath the transmittingheel 84 and are adapted tobethrown into operative position through partial rotation of the shaft109-by a link 11 1, connected by a bar 112 and a link 1.13 to the shaft102. Projecting from the side of eachof the transmitting-wheels 84 arefive stop-pins 114, corresponding in positions to the cam projections 98on the periphery of the said wheels. When the handle 108 is pulledforward and the shaft 102 partially rotated to throw back all of theshuttle-bars 68, the link 113, com-.

ting-wheel upon which the said stop- 'n is located Will rest in its zeroposition. I I will therefore be obvious that the bringing of each of thetransmitting-wheels to a position wherein one of its sto -pins 114 restsagainst a stop-plate 110 will ring all of the dials to register zero.

As shown in Fig. 2, thedials 88 are arranged on an angle facing theoperator, being covered by a raised portion of the casing 1, providedwith sight-openings 115. In order to make thedials 88 of suitable size,the same gay be shingled or overlapped, as shown in I do not wish to beunderstood aslimiting myself to the exact details of structure hereinshown and described,.inasmuch as the same may be varied Withoutdeparting from the spirit of my invention.
